Also known as stiff, reaper and ’thanatine.
Originally developed early in the millennium to facilitate research into near-death experiences. Betathantine induces a state as close to flatline status as is possible without causing gross cellular damage. It also reduces all emotional response almost to nil, originally to allow researchers to investigate near-death experiences without feeling.
Used on the street as an illegal substance by kids looking for a suicide-type experience, and in smaller doses to provide a mental detachment by reducing any kind of inhibiting emotions.
Betathanatine also has military applications as it can reduce human body temperature to ambient levels and simultaneously eliminate any emotional restrictions a soldier might be feeling, eg when asked to attack unarmed civilians.
